Example choice

Example choice is a teaching method that has been developed and explored at the University of Bergen. The main objective is to make mathematics and science teaching more interesting and relevant to the daily life of students. One study by Perkins, Gratny, Adams, Finkelstein, and Wieman found that interest in physics declined during a semester-long introductory calculus-based mechanics course. Whereas 19% of the students reported increased interest in physics, 45% reported that their interest in physics decreased. When interest increased, the leading reason was that students reported to see a connection between physics and the real world. Example choice aims to highlight the connection between formal principles and their relevance for everyday life in order to make school instruction a relevant experience for the child, as already John Dewey called for in his book "School and Society". For him, connecting instructional content to everyday life was the only legitimate way to make things interesting, as noted in his essay "Interest and Effort".

In traditional teaching, formal principles (laws, formula, problem solving procedures) in mathematics and science are often taught abstractly and then illustrated by an example. In example choice, by contrast, students are given multiple example tasks that all can be solved using the formal principle. The examples pertain to different topics, and each student is instructed to choose the most interesting example. This example is used to explain the formal principle.

For example, when teaching the joint probability of two independent events, teachers often explain the abstract procedure (p1 * p2) first and illustrate this procedure with an example (e.g., throwing a dice twice). In example choice, by contrast, teachers first collect or construct examples from topics that are of potential interest to high school students, such as contracting hereditary diseases, contraception, or winning in a two-step lottery to meet one's favorite artist. After the students selected the example that interests them most, they are given a problem related to the chosen example that they have to try to solve. After the solution attempt, the principle behind the joint probability of two independent events will be explained, using the chosen example. Teachers may then use the other examples in order to deepen the understanding of joint probabilities, for example by using worked examples.

A study observed that example choice increased interest in learning an abstract principle, and participants in the study invested more time to learn. In other words, students are the producers of learning. [1]

Example choice is difficult to use in traditional teaching because teachers often do not know the interests of their students. Even if they know these interests, a teacher would need much time and effort to find examples. With new technologies, teachers and students can help build a database of examples that users can retrieve when the formal principle has to be learned.

A pilot version of a database of examples, ExampleWiki, has been built to implement the principles of example choice.
